SEIKO PRESAGE COCKTAIL TIME OPEN HEART AUTOMATIC 2 TON GOLD BLACK

Key visual details:
Dial: Black with fine radial/sunburst or fluted texture radiating from the center. Applied gold-tone baton hour markers, gold dauphine-style hands, and the “SEIKO” logo at 12 o’clock with “Automatic” printed below the center.
Open-heart aperture: Large circular cut-out at the 9 o’clock position revealing the balance wheel and part of the automatic movement (a classic Seiko open-heart signature).
Case & bezel: Round polished stainless-steel case with a gold-tone bezel ring and gold-tone crown.
Bracelet: Multi-link two-tone stainless-steel bracelet (outer links steel, center links gold-tone) with a folding clasp.
Overall aesthetic: Elegant, dressy/business-casual style with strong contrast between the dark dial and gold accents.
Size information:
Official Seiko open-heart models with this exact layout (especially Seiko Selection SCVE-series or similar Presage/Coutura open-heart pieces) typically have a case diameter of 40–42 mm.
Most common matching references (e.g. SCVE053 and related black open-heart models) measure 42 mm case diameter × ~11.6 mm thickness.
Actual dial diameter is usually ~36–38 mm (slightly smaller than the full case size, as is standard).
This size wears as a classic mid-size dress watch — versatile on most wrists and balanced between presence and elegance.
